Just a thought, maybe iptables (kernel firewall) is blocking the port? Try this as root: # /sbin/iptables -F
And then try to telnet to the imap port. Note: This command effectively disables the firewall, use it only for testing. The rules are loaded from /etc/sysconfig/iptables at start-up, you can check that file. cheers, jad On Wed, 28 Apr 2004, Darren Cohen wrote: > > 1. no i cannot connect to the imap server from either side of the dmz. > > > > 2. i meant that the imap, imaps, and pop3 were all enabled. > > > > 3. my hosts.allow and hosts.deny files have nothing in them. > > > > 4. here is what my box is listening for: > > > > Proto Recv-Q Send-Q Local Address Foreign Address > > State > > tcp 0 0 0.0.0.0:32768 0.0.0.0:* > > LISTEN > > tcp 0 0 127.0.0.1:32769 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:993 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:99 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:995 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:143 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:111 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:80 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:22 0.0.0.0:* > > LISTEN > > tcp 0 0 127.0.0.1:631 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:23 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:25 0.0.0.0:* > > LISTEN > > tcp 0 0 0.0.0.0:443 0.0.0.0:* > > LISTEN > > tcp 0 138 192.168.1.102:23 69.143.104.198:49928 > > ESTABLISHED > > udp 0 0 0.0.0.0:32768 0.0.0.0:* > > udp 0 0 0.0.0.0:998 0.0.0.0:* > > udp 0 0 0.0.0.0:111 0.0.0.0:* > > udp 0 0 0.0.0.0:631 0.0.0.0:* > > Active UNIX domain sockets (servers and established) > > Proto RefCnt Flags Type State I-Node Path > > unix 2 [ ACC ] STREAM LISTENING 2586 /dev/gpmctl > > unix 11 [ ] DGRAM 1995 /dev/log > > unix 2 [ ACC ] STREAM LISTENING 2756 > > /tmp/.font-unix/fs7100 > > unix 2 [ ] DGRAM 6787 > > unix 2 [ ] DGRAM 6771 > > unix 2 [ ] DGRAM 2860 > > unix 2 [ ] DGRAM 2806 > > unix 2 [ ] DGRAM 2622 > > unix 2 [ ] DGRAM 2468 > > unix 2 [ ] DGRAM 2204 > > unix 2 [ ] DGRAM 2056 > > > > > > thanks for any help you may give me. > > > > darren > > > > On Apr 28, 2004, at 2:10 PM, Mark Crispin wrote: > > > >> On Wed, 28 Apr 2004, Darren Cohen wrote: > >>> I am trying to setup the imap server that came with redhat 9.
